rIhis invention relates to improvements in devices for removing gears orsimilar devices from shafts, and has for its object, to construct adevice of this kind that .will exert a drawing action to the ear to'which it is applied, longitudinally o the shaft on which the same ismounted. Y

Another object of my invention is to provide a device of this kind, thatwill completely house the gear tobe removed, whereby all possibility ofany lateral pressure during the removing of the gear which would resultin the bending or distortion of the shaft to which the gear is applied,is positively prevented.

A still further object is to provide a (ievice of this kind having aplurality of parts whereby the same will occupy y comparatively smallspace when not in use, but when the elements are assembled the partswill be securely held together by their frictional contact. A

Referring to the drawings, Figure 1 ,illustrates a horizontal sectionalview of my device applied to a gear wheel, Fi 2 is an v end view, Fig. 3i's a side elevation ofthe two piece housing, and Fig. 4 is a side viewof the drawing elements.

In thed-rawings, the numeral 5 illustrates a shaft, housed by a suitable,sleeve 5', said shaft having a tapered portion 6 on which. 40

the beveled gear 7 provided with acorrespondingly shaped taperedopening, is positioned, the end of said shaftterminatin in a threadedportion 8 to receive the usua nut for wedging the beveled gear' 4ontoits shaft. 'Ihe member which' houses'lthe gear' to be removed, comprisestwo sections 9 and 10, each of which is provided `with lateral bosses 11and 12 having-threaded openings -4 13 and 14, and it will be seen thatwhen said sections 9 and 1 0 are broughtl togetherv around a gear, theopeningsl and 14 aline i semi-circular inwardly extending flange 17 to.receive thel threaded members 15 and 16 which when screwed-holdthesections 9 and. 10 into engagement with each other. 4

Each ofthe ,sectionsis provided with a adjacent one of its ends, saidflange adapted to engage one end of the teeth of the beveled gear, whilethe opposite end of each respective section is provided with a' similarflange 18 which forms a shoulder to shaft 5.

Extending from the opposite end of said member 20 is a threaded opening21 communicating with the central bore, said opening 21 adapted toaccommodate the threaded bolt 22, which has a tapered end 23 engagingwithin a central recessed portion of the guard 24 said guard beingpreferably circular in form, and ofthe same diameter as the centralbore, whereby the same is sup ported in -alinement with the threadedbolt 22 at all times. The opposite surface of said guard engages the endof the shaft to which the device is applied, and thereby eliminates allpossibility of the bolt being distorted by the pressure of the bolt2,2when the same is rotated for dislodging a beveled gear.

To insure a direct longitudinal movement of the drawing element 20, Iprovide the same with'flat vsurfaces 25 which may be grasped by a wrenchor similar tool for holding the same against rotation when the threadedbolt is being operated.

In describing the operation of my device, attention is directed to Fig.l, which shows the same as-applied to a gear, and it will be seen thatby rotating the threaded bolt 22, to the right, pressure is exerted onone end of the shaft 5, and due to the threaded engagement between thethreaded bolt 22 andV drawing element the bolt and housing are moved inopposite directions with the result that the gear being removed isdislodged.
